$NetBSD: patch-vmhgfs-fuse_main.c,v 1.1 2022/01/30 16:22:20 pho Exp $

Workaround for an issue regarding write operations on vmhgfs. See:
https://github.com/vmware/open-vm-tools/issues/437

Ideally this should be worked around by setting fuse_conn_info.max_write to
65457, but it doesn't work on NetBSD because neither PUFFS nor ReFUSE
support it at the moment.
